Primary cultured astrocytes were pretreated with GVT followed by treatment with a proteasomal inhibitor MG-132. Treatment with GVT alone increased the Nrf2 protein to certain extent. However the MG132 treated cells expressed increased levels of Nrf2 protein (A). Quantification of the band intensities of Nrf2 normalized against actin (B). Data were obtained from three independent experiments and analysis of variance was done by employing Tukey test. *p<0.05 vs. control was considered statistically significant. Error bars represent mean ± SEM.
